mean free path is like riding a bumper car

Categories: Comparisons

An example of a teaching analogy:

"The mean free path is the average distance which a molecule travels between collisions with neighbouring molecules. This is like riding in the bumper cars at a carnival: you only can travel a short distance, on the average, before being involved in a collision with another bumper car."
